EJB 3.1 PFD2 (Feb 24, 2009) 4.4:

java:global[/<app-name>]/<module-name>/<bean-name>[!<fully-qualified-interface-name>]

While currently handled by proxy-impl, we've discussed moving the JNDI binding bits out.

The location by spec is the same as presently used by JBoss EJB3, with the exception of the delimiter before the FQN.
